<em>A) (-5,7)</em>
Step-by-step explanation:
<u>Functions and Relations</u>
A set of values A can have a relation with another set B as long as at least one element of A has at least one image in B. Functions are special relations where each element of A (the domain of the function) has one and only one image on B (the range of the function).
By looking at the options, we can see that x=9, x=-8, and x=-1 already have defined values in Y, so if we define another value for any of them the relation will stop being a function. The only possible choice to preserve the function is the option

answer: it would be one solution, becasue the variables are different and the constants dont matter, since the variables are different
Answer: C = 2 + 0.25 D
Step-by-step explanation:
Hi, to answer this question we have to write an equation:
The cost of the cab ride (C), must be equal to the fixed fee (2) plus the product of the charge per mile (x) and the number of miles traveled (D)
C= 2 + Dx
Since the cost for a 50 mile ride is $14.50:
14.50 =2 + 50x
Solving for x:
14.50-2 = 50x
12.50 =50x
12.50/50 = x
0.25 = x
The cab company charges $0.25 per mile.
Back with the original equation:
C = 2 + 0.25 D
